I have tested SL5.3RC1 on my Proliant testserver with sata RAID configuration (Promise FastTrak Sata150) and was pleased to see that SL had little trouble with it (where Fedora 11 alpha (!), Debian 5.0 and SUSE Linux Enterprise Desktop 10 failed to detect and configure it). RHEL, SL and CentOS seem to have no problems with it (SUSE complained that only a 2.4 kernel would support it, a 2.6 kernel would not?!?). One thing I came across (just with previous versions of RHEL, SL, CentOS, etc.) is the problem that not all monitors are automatically/correctly detected. This results in problems when you reboot into graphical mode after the installation (firstboot has no problems). Details are in the bugreport (https://www.scientificlinux.org/bug.feature/bugs/15/pcng_issue_view). Would it be an idea to make notice of this in the release notes (section "Issues"?). I do not mention this bug (again) to argue with people who don't seem to have this problem (and keep informing me I have something isolated), but rather because the new Fedora 11 alpha seems to solve this problem by introducing a "install with default driver" option with the grub menu on their installation dvd. That was a good idea, because where RHEL/SL/CentOS didn't give me graphical problems during install, the new Fedora did also mess up my graphics during the graphical installation (unless I selected the "default driver" option). Hope it is helpful. Regards, Patrick
